LORING GOES, OF WORCESTER, MASSACHUSETTS.

WRENCH.

SPECIFICATION forming part of Letters Patent No. 229,673, dated il'uly6, 1880.

Application filed May 17, 1880.

To all whom it 'may concern Be it known that l, LORING GOES, ofWorcester, in the county of Worcester and State of Massachusetts, haveinvented certain new and useful Improvements in Wrenches; and I declarethe following to be a description of my said invention sufficientlyfull, clear, and exact to enable others skilled in the art to which itappertains to make and use the same, reference being had to theaccompanying drawings, which form a part of this specification, and inwhich- Figure 1 represents a front view oi' a screwwrench constructed inaccordance with my invention. Fig. 2 represents a side view ofthe same,one side of the handle being removed to show the internal construction.Fig. 3 is a perspective view oi' the bar, shank, and key. Fig. 4 is atransverse section at line rw w. Fig. 5 is a transverse section at linewas. Fig. Gis a transverse section at line y y, and Fig. 7 is a sectionof the handle-frame only at line no an. Fig.8 is a section of thehandle-frame only at the line z z.

This invention relates to that class of wrenches known as the Goesscrew-wrench 5 and it consists in certain improvements in theconstruction of the handle and bar-shank and the method of combining andattaching said parts together, as hereinafter explained.

In the drawings, A denotes the wrench-bar,

n provided with a head, B, and supporting the sliding jaw C, operated bythe rosette-screw D, in ordinary well-known manner, and thereforerequiring no further description herein.

The shank of the bar ismade, as shown in Fig. 3, with a reduced portionA', about onethird (more or less) of the thickness of the iull bar, flatupon the sides, and having its edges a, which are longitudinallyparallel, or nearly so, milled off on the are of a circle, or of cy--lindrical form, the milled portion being also extended onto the thickpart of the bar, as at c, for a short distance, forming shoulders d d atthe front and rear sides, against which the end of the handle abuts. Acentral longitudiy nal slot or opening, f, is formed through the shank,as shown.

The handle is made with a metal central frame, E, to which are fittedwood side plates, F, the parts being constructed and arranged (Nomodel.)

as follows: The upper and lower ends of the metal frame E are made thefull size or thickness required for the handle, while the intermediateportion is made thinner, and of about the same thickness as the reducedpart of the bar-shank, the central portion being open to receive saidbar-shank and to lighten the weight oi' metal. The upper end of theframe E is made square to t against the shoulders d d ot' the bar A, andhas the usual projection Gr to support the end of the rosette-screw D.

Cross plates or bars H are rigidly fixed upon the frame E, preferablycast integral therewith, and joining its two sides, e e, in the mannershown, and the said sides c c are formed concave on their inner faces toiit closely to the rounded edges of the bar-shank A th roughout thelength ot' the latter. These inner edges 'are iinished by driving abreaching-tool in at the upper end and down to the enlargement at thecenter of the handle-frame. They are thus made to tit accurately andiirmly to the i milled edges a on the bar-shank A".

A Wedge pin or key, I, is driven through the opening fot' the bar-shankat the back of the cross-pieces H, which key I draws the shoulders diirmly against the end ofthe handle and locksthe parts securely inplace, so that the bar Aand handle-frameE are as firm and. rigid intheir connection as it' solid or made in a single piece.

The key-seat i 011 the cross-bars H is milled out after the top end ot'the handle-frame is squared oft", so that the distance will be uniformon all handles, and the end seats, m,- for the wood side plates, F, maybe dressed out with a circular milling-tool, so that all will be alike.The wood side pieces, F, which may be turned in pairs on a pattern-latheand then separated, are fitted to the sides of the metal frame E, andare retained in position by the screws or rivets K, extending throughfrom side to side, as shown, one passing through the opening f of thebar and the other through a hole in the cross-brace of the frame, asillustrated. The exterior ofthe handle is finished smooth and of an ovalform at its ends, so as to project but little on the sides at itsjunction with the bar A, the central portion being nearly round.

The key I may be made with rounded or IOO square bearing-sides, aspreferred, and could be arranged through instead of at the back of thecross-pieces H, if desired.

By constructing' and arranging the parts in the mannershown anddescribed, a very stron g, serviceable, and desirable wrench isproduced,

which can be manufactured with facility andl at a moderate cost.

What I claim as of my invention, and desire to secure by Letters Patent,is

l. The handle-frame E, provided with crosspieces H and chise-littingconcaved sides e c, in combination with the bar A, having' thereducedshank A', with rounded edges a a, shoulders b, and opening f, and thelocking-key I, arranged as set forth.

2. The combination, with the bar A, of the within-described handle,composed of the me tallicceutral frame, E, having close-fitted sides eo, with cross-bars H, secured to the bar-shank by the locking-key 1,'and the wood side plates, F, fitted to said frame for inclosing saidkey, and secured by the circular end seats, m, and screws K, as shownand described.

Witness my hand this 13th day D. 1880.
